Since they don't involve force fields, I'm sure that my suggestions will disappoint you: Thesis: The pursuit of more powerful and more accurate modeling tools (both nice to be sure) makes us overlook two aspects of modeling that make it meaningful to chemistry as a whole: accessibility to large numbers of chemists, and sufficiently easy to use that one can *play* with models and ideas. In this spirit, I would say the biggest improvements since 2000 have been: 1. spread of powerful, e.g., DFT-based, modeling tools to desktop computers 2. much greater adoption of computer modeling software by textbook authors (still a work in progress b/c the authors use only a fraction of the software's capabilities, and the teachers use only a fraction of what the authors produce) Happy New Year! -Alan William Lingran Chen lchen|*|mdli.com wrote: >Sent to CCL by: William Lingran Chen [lchen]_[mdli.com] >Recently Perry post a news "Researchers at Los Alamos National >Laboratory have set a new world's record by performing the first >million-atom computer simulation in biology."

Lao Tzu 22 From owner-chemistry@ccl.net Sat Dec 24 21:38:01 2005 From: "Wenjun Zheng zhengwj:-:helix.nih.gov" To: CCL Subject: CCL: Announcement of a new web-server for analysing protein dynamics Message-Id: <-30392-051224204805-26503-O2JaOrffflujykOLamF5fw*o*server.ccl.net> X-Original-From: "Wenjun Zheng" Sent to CCL by: "Wenjun Zheng" [zhengwj[]helix.nih.gov] Dear researchers on protein dynamics: The Laboratory of Computational Biology at NHLBI/NIH is happy to present a new web server (AD-ENM) for analyzing dynamics of protein structures based on the elastic network model. The server is now available to public users at http://enm.lobos.nih.gov. So far the functions of AD-ENM server include: 1. Describing collective protein conformational changes using low-frequency normal modes; 2. Predicting protein conformational changes induced by given local structural deformations (caused by ligand binding); 3. Identifying key residues which are dynamically important to a given functional site. The AD-ENM is still under testing. You are very welcome to try it and report any bugs or drop any comment to me by email (zhengwj ~~ helix.nih.gov). More functions will be added in the future. Thank you for your attention!
